​Heaven is hotter than Hell

The Temperature of Heaven described in the Bible:"Moreover, the light of the Moon shall be as the light of the Sun and the light of the Sun shall be sevenfold as the light of seven days." Isaiah 30:26

Thus Heaven receives from the Moon as much radiation as the Earth does from the Sun, and in addition sevenfold as much as the earth does from the Sun, or 50 times in all.

Using the Stefan-Boltzmann fourth power law for radiation (H/E)4 [fourth power] = 50, where E is the absolute tempetare of the Earth, 300°K (273+27). This gives H, the absolute temperature of Heaven as 798°K absolute (525°C)

The Temperature of Hell as described in the Bible:"But the fearful and unbelieving...shall have their part in the lake which burneth with fire and brimstone." Revelations 21:8

A lake of molten brimstone (sulfur) means that its temperature must be at or below boiling point, which is 444.6°C. (Above that point it would be vapor, not a lake.)
